How To Fix Slow Startup Times In macOS (4 Ways to Speeding It UP)

A three-year-old computer that can perform as fast as it did on its first day is like a Big Foot of the tech world. It’s almost impossible to see, and there are many others claiming that they have seen one but are unable to show any proof. It’s taxing to have to wait for a computer that’s slow as a turtle and it’s even more annoying if it takes longer to start up.

Macs are no exemption from slow down issues. No matter how high-end your MacBook Pro is, it will be prone to performance issues after a year or two. One of the initial signs of a MacBook Pro that’s past its prime is if it begins to load slowly. If you think your old buddy is no longer what it used to be, then let us take you through some of the reasons why it’s happening and what you can do to fix it.

You Have Disk Drive Problems

Macintosh HDDs and SSDs are prone to disk drive problems. Whether it’s through a virus or through old age, yours will have issues after some time. According to softwarefavorite findings, When you have problems like this, it’s not just the startup that slows down, it’s also everything else that your MacBook Pro does that becomes more taxing. As such, it’s important to remedy this issue as soon as possible.

Head to Finder, then go to Applications, and then Disk Utility.

The next step varies depending on your current OS. For OS X Yosemite or lower versions, look for the First Aid option and check the two buttons at the right corner of it. These are Verify Disk and Repair Disk. The first option will locate any issues in your disk and the other will fix those issues.

For Macs that run on OS X El Capitan, macOS Sierra, High Sierra and Mojave, you don’t need to look for Verify Disk and Repair Disk. All you need to do is click First Aid and both processes will be done if necessary.


As we’ve said, there are limits to your disk drive and even if you take care of it, it will eventually succumb to issues. The good thing is that disk drives are replaceable. One of the best ways to fix your hard drive or disk drive is to simply replace it with a new one. SSDs like the Samsung 860 Pro will work wonders on your MacBook Pro’s overall performance.

You Have A Long List Of Login Items

Login items are essentially apps and software that launch immediately upon startup. Some of these logins are crucial but as you begin installing new programs or extensions on your browser, your MacBook Pro will have more login items to process as it starts up. Luckily, there is an easy fix to this common problem.

Look for the Apple logo on the top left corner of the screen and from there, select System Preferences.

Locate Users and Groups and proceed to it.

Once the new page opens, look for the Login Items tab which is next to “Password”

You’ll see a list of apps that run when you turn on your MacBook Pro and click the ones you don’t need.  Ideally, you want to look for app services like AmazonMusic, Adobe CreativeCloud Helper, and more.


There are some third-party software that can help you organize your login items. The best example we can give you is CleanMyMac. Simply download this app and from its menu, you can check the unnecessary login items on your MacBook Pro and disable it from there.

You Are In Need Of An Update (Or Have Just Updated)

Every once in a while, the people over at Apple will launch an update for MacBook Pros, or more specifically, its OS. The general purpose of these updates is to simply fix some issues or to add new features to the current OS. If you’re OS is not up-to-date, there’s a good chance that this can cause a slower startup on your end.

Check online if there are any updates on your OS.

If there is one, simply restart your MacBook Pro and it will automatically update to the latest OS version. Make sure that your MacBook Pro won’t get shut down mid-update as this could cause more performance issues.


If you’ve just updated your OS and your MacBook Pro is slowing down, then you may have another issue at hand. We’ve found that several restarts will keep your MacBook Pro’s performance up-to-par with the recent update.

Your Hard Drive Is Full

Whether it’s the latest version of a Samsung laptop or a year-old MacBook Pro, all computers will slow down if it is running on a hard drive that’s almost full. Your MacBook Pro will not only slow down upon startup, but it will also poorly perform everywhere else. The good thing is that this issue is easy to handle.

Browse through your folders to delete files you don’t need. Most of these you’ll find in your Downloads folder. If you don’t want to let some videos and pictures go, simply upload them to your iCloud.

Use programs like CleanMyMac. This program has a feature that detects all junk files that you can delete easily.

You may also want to head to your browsers and clear caches, history logs, and extensions that you don’t need. These take up space on your hard drive as well.

Ideally, you’d want to make sure that your hard drive has at least 20% free space. This will keep your MacBook Pro’s performance consistent all throughout. If you are like many others that need huge disk space, we recommend buying an external hard drive to keep some of your files in.

These are just some of the possible issues that your MacBook Pro could have which results in a slower startup. If you want to avoid these problems in general, do regular checkups on your storage, disk drive, and more. Alternatively, using helpful cleaning apps can ensure that your MacBook Pro is as optimized as always.
